--- Comment #10 from Jörg Höhle hoehle@users.sourceforge.net 2012-02-22 13:10:44 CST --- The audio/video cut off/stall bug is still present in wine-1.4rc4, exactly as described in my initial comment. The stalling of movement is very noticeable.
I could test that by setting: Plugin=RenderSystem_Direct3D9 in bin/release/plugins.cfg, but that causes the black screen bug #21351 once the adventure starts. Bug #29975 is split from comment #9 about the inability to instead use: Plugin=RenderSystem_GL
FWIW, the bug was also present in wine-1.3.24.
